I have started watching the Video Lessons under the Learning section and realized that chess.com is actually serving up the videos rather than having them hosted by a content delivery system such as Akamai for example.
I am wondering if there is an actual need for a CNS at this point as maybe not too many of the videos are requested and therefore it is not perceived as a bandwidth drain.
I have noticed some lag and the video is downloading but nothing I'd worry about at the moment.
Does anyone watch the videos? As I said I have started to and am finding them useful.
